- This invention relates to new and useful im rovenients in sleds- I t is the object of this invention, among other things, to provide a sled wherein the 5 runners will have'the maximum flexibility; will be easily guidedvor steered jandhave means for checking or brakin'gits' movement as well as to produce a sled having the'maxicapable of fwith standing constructed with the s andproducedat the mum strength, Nrough and hard usage, fewest possible part minimum cost. I I I I V 'Tothese, and other ends; my invention consists in the sled', having'certaindetails of will'be hereinafter described and more particularly pointedoutin the claims.

' Referring to the drawing's,-in which like numerals of reference indicatelike parts the several figures;

Figure 2 is'a viewof the underside thereof with the runners flexed in one-direction Figure 3 is a side elevation thereof;

*Figure 4=is an enlarged transverse sectional view, the parts in section being taken substantially on the plane indicated by the line 44 of Figure 1; I v Figure 5 is an enlarged transverse sectional View, the parts in section being taken substantially upon the plane indicated by the line 55 of Figure 1;

Figure 6 is a view of a modified form of the steering bar; and

Figure 7 is an enlarged cross sectional view of one of the runners. I a 1 Having reference to the drawings, the numeral 10 designates the runners constructed substantially of inverted T shape rails, with a contact strip '11 upon the underside thereof. These runners are turned upwardly at their forward ends and connected by the pins 13 or the like to the head bar 12. These pins are preferably securedlto one of the parts and project through a slot 14 in the other part.

Fixed on'the runners are the standards'15 and 16, to'the former of which is secured'the' cross bar 17 and to the latter the cross bar 18.

w of my improved "that-project upwardly upon each side of the A nected withthe adjacent crank arm'29 by a l inwardly projectingihandles 44 at each end Upon each side of the sled,above the run- H ners are the side bars19,'each of which is secured at its frontend between the 'runner 10 and-head bar'12 and joined near their rear ends by the cross bars 20 and 21. Sidefflf rails 22 and platform boards 23 are secured to these cross bars and'to cross-barl8f Connected with the cross'barf18 are the saddles 24 f -which are formedwith wings 25 side rails 22*and' wings 26, which form a journal for the shaft27, upon which is fixed the crank arm 28 and crank arms 29. v Attached to the head bar'12 is the plate 30, and between which and the 'draw bar 31 is the link 32 having a slot 33 therein into which projects a guide pin 34. The rear end ofthe draw bar 31 is pivotally connected with the crank arm 28 at the face portion 37 and is providedwith a slot 35, into'which pro--= jects a'guide' pin 36 fixed in the cross bar 17 A bracket 38 isfixed'to and near the rear end of each of the runners 10 and-"pivotally connected therewith is a brake bar 39 conlink 40-. The inwardly projecting-portion of the base of eachof the runners 10, opposite the brackets, is cut away at '11 to receive' the brake'bar 39. Thus the inner face of the latter does not project beyond the outer edge' 0 of the base of the runner; thereby minimiz- "ing the possibility of dama e or injury to'the I brake bar 39" and 'inter' erence with the smooth running of the sled.

' Secured to the'l k 32is a steering bar 42 of conventional form.' In Figure 6' Thave shown a modified form of this bar, which is thereindesignated 43 and is provided with thereof. With this form of'steering'bar; the v 7 hands when grasping the handle 44 are'pro- 'tected by the guard portions 45 against-injuryiflthe steering bar should meet anobstruction. I V As the rear end of the draw bar 31'is fixed against lateral movement; the/swinging of the steering bar 42 causes the forward end {thereof tomove laterally about the center-of the connection at the crank arm 28. Through the cr os sbar 17 thismotion is transmitted to Q the runners so that in one of their extreme positions they occupy the planes substantially as shown in Figure 2. When flexed, the runners move about the axis of the pins 46, each of which connects the standard 16, cross bar 18, side rails 22 and saddle members 24 7 together as a unit In the head of each of the standards 16 is a slot 47, through which projects the pin 48 fixed in the cross bar 18.

Between the standards 16 and cross bar 18, are the Washers 49' upon the pins 46 and 48, having washers 50 adjacent to the heads thereof, substantially as shown in Figure '5'.

Movement of the steering bar 42 forward causes the draw bar 31 alsoto move forward, and through its connection with the crank I arm 28 rock the shaft 27, and through the links 40 move the brake bars 39 to-their brake position, illustrated by broken linesin Figure 3, at which time the nose thereof projects below the runner and into thesurfaceover whichthe sled istraveling.

I have provided means whereby this bar 31maybe held against forward movement if desired, comprising a rock lever 51 pivoted to the cross bar 21, having a handle 52 at one end under one of the side rails 22 anda plate .7 53 at the other, end, which is heldnormally in its-upposition by a spring 54. On the draw bar 31 adjacent to the plate 53 is a stop member 55. Vhen the handle 52 is pulled upwardly the plate 53 is moved downwardly and in front of the stop member 55, thus preventing forward movement of the draw bar.

The strip 11 upon the runners adds strength to the runners without affecting its lateral flexibility and also provides a contact 7 surface of relatively narrow width.

The flexibility of the parts is facilitated when there is a weight upon the platform by an antifriction mechanism, which comprises a pair of rolls 56 journaled upon studs 57 within recesses 58 in the cross bar 17. These rolls are journaled so that a portion thereof projects above'the top of the cross bar 17 (see Figure l) and contact with the rail 59,

attached to the platform boards 23 and carry the platform and the weight thereon. This the runners; a cross bar connected with the last mentioned pair of standards; and antifriction rollers between the cross bar and platform to facilitate the lateral movement of the cross bar.

2. In asled; a bodymember; a rock shaft supported relatively. thereto; runners connected with the body member; a draw bar connected with each of the runners near the rear ends thereof; a steering bar; a connection between the steering bar and rock shaft 7 whereby a straight line movement of the site end, a cross bar movable relatively to the platform, having a fixed connection with the runners between its ends and means for moving the last mentioned cross bar laterally and thereby flexlng the runner between its endsin substantially parallel lines, comprising a rock lever fixed near one end and having an operative connection with the last mentioned cross bar, and a manually actuated rock member connected therewith whereby movement of the latter will be transmitted to the rock lever and through the cross bar to the runners which will thereby be flexed in substantially parallel and curved linesbetween the ends thereof.

In testimony whereof, I have hereunto affixed my signature.

insures an easy and practically frictionless lateral movement of the runners.

Within the scope of the appended claims -minor changes and alterations may be made with n my invention, and I would therefore V 'haveit understood that I do not limit myself to the exact construction herein shown and p described.

Having described my'invention, what I claim as new and desire to secure by Letters Patent, is

1. In a sled; a body having a platform as part thereof; flexible runners associated with the body; standards arranged in pairs and associated with the runners to support the platform, one of such pairs of standards being adjacent to the longitudinalcenter of
